What is material master?
Material master is a master record in sap which stores a lot of data about a material,which will later use in transaction records in order to reduce to time and manpower .
How to create material master?
How to create material master?
We can create material master record in two different types,
1st is by following the path given below.
Sap menu-logistic-material management-material-create(general)-immediately
The 2nd method is by using the transaction code(t-code) MM01 directly in the transaction field.
Here i am going to show you a detailed material master from MM prospective.
MM01
Material:material number can be assigned by the system internally or externally by us,depending the customization
done in MMNR t-code.
In std sap R/3 material number can be maxed up to 18 digits
& in case of S/4 hana it can be up to 40 digits.
Industry sector:the industry we are working on.
It's customization can be done in OMS3 t-code.
Material type:its a grouping of material as per our requirement.We can create new material type in OMNS2 t code.(some common std sap material types:ROH-raw material,FERT-finished product,HALB-semi finished product,HAWA-trading goods,FRIP-Perishables,DIEN-services)
choose your desired material type and industry sector and click select views👍👇
Select views like basic data1,basic data 2,purchasing,general plant data/stogare 1,general plant data/storage 2,accounting 1.
MRP views are also related to MM,but we will later discuss about those.
Click org levels and select our plant and storage location.
Click enter or
Fill up basic data 1 view as follows;
Basic data 1
Base unit of measure:With this unit we store material in our warehouse.(CUNI-can create new unit of measure.)
Material group:Its also a categorization of material,but it's only for our information purpose .(OMSF-can create and customize material group.)
Old material no:It's the number which was being used in the previous ERP/in Legacy system.
Ext.mat group:It's the material group of our product in vendor system.
X-plant material status:It represents as a two digit alpha-numeric number.It shows that material is blocked for procurement or for storage or for sale.We can customize it as per our requirement in OMS4 t code.It maintains at co.code level i.e. relevant to every plant under that company code.
Gross weight,Net weight,Volume ,Size/dimension can be given as shown in figure.
ENA/UPC:International Article No/Universal Product Code.
it's a code assign to every product uniquely.
UPC wiki
Maintain basic data 2 view
click enter it will take you to Purchasing view.
Purchasing view
Order unit:If we are ordering this product other than base unit of measure then we can maintain here.
Var.OUn (variable order unit):If we are planning to change order unit during PO we can enter here,we can choose the options here.
Purchasing group:It can be group/person/company which helps us to buy this product.It is not a part of MM organisational structure and can buy product for anyone.So it is called to be a floating entity.It represents as a three digit alpha-numeric number.(OME4-t code to create purchasing group)
Plant specific mat status:Its the material status relevant to the specific plant(plant which is given during the creation of material master).
Quality free goods:Here we can decide that this material can have free product or not.
Automatic PO:If you want to create automatic PO for this product in future,then you have check mark this.
Shipping inst:We can customize it in OMEK t code.Here we create certain rules for vendor to follow while delivering the goods and we assign points to vendor during GR based on this shipping inst customization.
N.B:Minimum point can be assign to vendor is 1.
Purchasing value key:(OME1)It shows reminders,under and over delivery tolerance and shipping inst.
system will send reminders to vendor as shown below figure.
GR processing time in days:Number of days required to do inspection of material and to place it in store.
Post to insp stock:if checked material will be posted as quality inspection stock after GR.
Critical part:It specifies that material is an important material for us.
Source list:If checked source list(it's another master record)is mandatory to maintain for this material,which contains the list of source of supply(source of supply:who can supply goods/services in a particular time period,here source of supply can be a vendor or can be plant.)
Plant data/storage 1
Unit of issue:If we are issuing material from warehouse other than our base unit of measure,then maintain here as required.
Temperature condition:If material has to be stored in a particular temperature then maintain here and customize it in OMS7 t-code.
Storage condition :If any kind of special storage condition need for this material then we can customize it in OMS6
t-code.
Container requirement:If any special kind of container required for transportation then customize it in OMS8
t-code.
Batch management:If material is going to be stored in batches then its pre-requisite to select the batch management indicator here.Batch management is an important chapter itself and we will know about it in future blogs.
Maximum storage period:Its the longest time duration for which we are allowed to store the material.
Total self life:Its the duration from the date of production to the date of expiration.
Plant data/storage 2
Negative stock in plant:
It's a logic we may need while doing plant business.Through this logic we can issue stock from warehouse to relevant department with the deficit of actual stock in warehouse.
Accounting 1
Valuation class:
Grouping of materials by same account determination is called valuation class.Valuation class helps us to post material value to the relevant material G/L account.
price control:
S:'S' stands for standard price,prices which don't change easily and we have the control of the price then we can go with standard price.Predominantly we use standard price for finished and semi-finished product.
V:'V' stands for moving average price,prices which fluctuate time to time & we don't have the control on the price,most of the raw materials which we buy from vendors can maintained with price control 'V'.
maintain our desired priced and save(ctrl+s).
Here we have discussed the base of material master.I hope it will help you to understand material master a little better.
